The aim of the present study was to assess the ability of different white-rot fungi to tolerate polychlorinated biphenyls (PCBs) using predictive mycology, by relating fungal growth inhibition to ligninolityc enzyme secretion. Fungal strains were grown in the presence of PCBs in solid media and their radial growth values were modelled through the Dantigny-logistic like function in order to estimate the time required by the fungal colonies to attain half their maximum diameter. The principal component analysis (PCA) revealed an inverse correlation between strain tolerance to PCBs and the laccase secretion over time, being laccase production closely associated with fungal growth capacity. Finally, a PCA was run to regroup and split between resistant and sensitive fungi. Simultaneously, a function associated with a model predicting the tolerance to PCBs was developed. Some of the assayed isolates showed a promising capacity to be applied in PCB bioremediation.Abbreviations: Polychlorinated biphenyls (PCBs), white-rot fungi (WRF)

“…Researchers are now focusing on white rot fungi for use in bioremediation processes since these organisms have the ability to degrade a wide range of environmental pollutions (Fu and Viraraghavan, 2001;Paszczynski and Crawford, 1995;Pointing, 2001;Shah and Nerud, 2002). The decolorization can be achieved either by adsorption or oxidative degradation by the enzymes (Fu and Viraraghavan, 2001;Knapp et al, 1999).…”

This study focuses on treatment of landfill leachate in column experiments by immobilized Trametes versicolor on polyurethane foam, collected from Nonthaburi landfill site, Thailand. In this study, glucose was used as a co-substrate. The effect of biomass growth on color removal was observed by immobilizing fungi on polyurethane foam. The same immobilized fungi were used for four cycles of 5 days each to find the reuse of fungi. Leachate was diluted to see the effect of organic loading on color removal. At optimum pH of 4 and in 20 days with 3 g/L of glucose, the fungi could decolorize 78 % and 63 % for 5-times dilution and concentrated leachate, respectively, using immobilized fungi after 4 days initial growth. Fungi could also reduce biological oxygen demand and chemical oxygen demand of 52 % and 42 % (with initial biological oxygen demand and chemical oxygen demand of 48,900 and 96,512 mg/L), respectively, with glucose 3 g/L in concentrate leachate and with 4 days initial immobilization of fungi on polyurethane foam. About 1-6% higher color removal was observed on day 20 with 15 days fungi immobilization initially as compared to 4 days immobilization. Higher removal efficiency was observed for the same leachate after dilution due to reduction in organic loading. Addition of co-substrate enhances significantly removal of color, biological oxygen demand and chemical oxygen demand. Chemical oxygen demand removal reached to 0.6 mg/mg of biomass with the co-substrate. Therefore, white rot fungi can be considered as potentially useful microorganisms in landfill leachate treatment.

“…glycines in the process of decolorization of anthraquinone dyes: RBBR and Poly R-478. Lignin peroxidase next to laccase was accepted to be the most important ligninolytic enzyme of white-rot basidiomycetes (Paszczyński and Crawford 1995;Robinson et al 2001;Martinez et al 2005). In the course of our study, we found that the level of LiP activity reached highest value in cultures of microfungi with lignin.…”

“…Participation of the non-specific HRP-like peroxidase in the biodegradation of post-industrial of lignin was reported in the paper by Korniłłowicz-Kowalska et al (2008) concerning the anamorphic stadium of B. adusta CCBAS 930. In cultures of numerous lignin-degrading white-rot fungi, the manganese-dependent peroxidase is also detected (Paszczyński and Crawford 1995;Martinez et al 2005). The lignin-(LiP) and manganese-dependent (MnP) peroxidases were produced also by 23 strains of ascomycetes degrading lignin-cellulose, in particular from the genus Coniochaeta (Lopez et al 2007).…”

A total of 610 strains from 16 species of micromycetes with potential ligninolytic capabilities were isolated from soil, compost, and rotten wood, including 400 strains of soil origin. In the test of decolorization of agarized 0.06 % alizarin blue, 52 strains with high decolorization activity were selected. In liquid cultures with 0.2 % post-industrial lignin and 0.03 % alizarin blue, all of the selected strains showed three different extracellular peroxidase activities such as HRP-like, LiP, and MnP. Laccase was detected only in the cultures with alizarin blue, but those were trace amounts. In the decolorization of alizarin blue, the highest levels of activity were attained by HRPlike peroxidase. In the transformations of post-industrial lignin that included decolorization, colorization (darkening of substrate), and re-colorization, the highest levels of activity were attained by lignin peroxidase, especially at the start of the culture. The transformations of both dye substrates in the cultures of all 52 strains were accompanied by the release of glucose oxidase, but high activities of that enzyme were observed only in the presence of alizarin blue. Whereas in the presence of lignin the fungi under study synthesized catalase, the activity of which attained a maximum toward the end of the culture was negatively correlated with the activity of the remaining oxidoreductases under study. Among the 52 selected strains, three strains such as Haematonectria haematacocca BwIII43, K37, and Trichoderma harzianum BsIII33 were characterized by a high activity of decolorization.
